To all whom 'it may concern l t Be it known that I, HARRY E. Dn VAUGHN, a citizen of the United States, residing at ,Morgantowm in `the county of `Monongalia supported upon apedestal with all of the drive and rotating mechanism set in a deep cellar, and as a consequence, when repairs of any kind are necessary, as isA often the oase, the operator must stop work and cool the oven off so that workmen may go into the cellar, underthe wheel, in `order to gain access to the parts to be repaired. Thus,

repairs are not only difficult by `reason of the inaccessibility `of the parts, b-ut each time that repairs are necessary a" financial loss is entailed by reason of the shuttin downof the apparatus. ,i e

One of the objects of the present invention is to overcomethe foregoing objectionable features by providing a flattening oven with a wheel having all of its driving mechanism outside ofthe oven, and above the same, away from the heat,fand easy `of access for `the purpose of making repairs ject is to provide `a flattening ovenhaving a wheel suspended from asuitable support, located at a pointiwhere the temperature of the oven canhave no effect detrimental to the perfect and elicient operation of the parts atalltimes. A further object is to provide a flattening oven having a suspended wheel, and means whereby `the `said wheel may be operated ,either` by` `mechanical power or manually, as may be desired or necessary.` A further object is to provide af flattening oven having a suspended wheelso supported that it may be raised or lowered in the oven, to regulate the clearance "between the face of the flattening stone and the clay mantel or dividing walls in the oven, without changing the relation of the master gear `wheel to the driving pinion. A further object is` to prof vide a flattening `oven having a suspended wheel, and means for positivelyl `adjust- Specification` of Letters Patent;` Paf Application leli October 6, 1916. iSerial No. 124,093.`

further object is to provide a iiattening oven so constructed that deep and expensive cellars `are rendered unnecessary. A further object is to providefa flatteningoven havingitsmantel walls andcap suspended from i i i all `@Xternalsupport.` a e e "The invention willbe hereinafter `.fully "set lforth 4and particularly` pointed out V in utheclaims. "l if H f :In ,the accompanying drawings if .i f y Figure@ `is `a transverse sectional view of a flattening oven, illustratingthe invention. Fig. 2 is a planyview of` the iiattening oven, the inantelivalls being shown` in t `dotted lines and in section. Figa 3 `isa top plan View illustrating `the `driving mecha ,nism for the wheel.v Fig. "4 is a sectional viewlillustrating a `slight modification; Referring to thefdrawing, 10 designates a flattening oven, which maybe of any preferred construction, Ithe same `being proa vided pwith the shovepan track 1l, burners l2, and thezmantlefwalls 13, dividing, the oven into the heating chamber and flattening "compartment le, annealing chambers l5 and 16, andpiling compartment 17.` EX- tending throughthe compartment '16 are the leer rods 18.

,v Resting upon `the furnace walls, is asup portingframe` formed of `beams l5), connected by suitablecross pieces 20, and secured to said frame are` the beams 2l,which sustain "the weightfofthe ,flattening wheel 22. `Said wheel is keyed, or otherwise se` cured to the` shaft` 23, the lower end of `which isyrotatably, inountedin a bearing tainedlinuaJ `central position hy"`means `of guy` rodsl26," attached to the sleeve and eX tending through the wall of the oven, being provided with e means, "illustrated at 27,

whereby` the tension upon said guy rods Imay" be adjusted. `The upper end` of the sli-aftl 23, `is passed through and splined to a master gear wheel 28, the hub ofwhich sleeve24, preferably provided` with antie friction bearings 25,;"saidsleeve being inain- 33, interposed between the master gear wheel ,28 andsaid labutment ycollar 33, serving tofresiliently supporty the Weight of the flattening wheel 22 and its shaft 23; By

means of the nut 31, the wheel 22 may bem adjusted to the proper level within the oven to increase orvdecreasethe clearance between the fiattening stones 34 and the mantely walls 13. v

Meshing with the master gear wheel 28,

is a pinion' 35, secured to a drive shaft 36, connected up in suitable manner "with a motor of any preferred type, an electric motor being` conventional-ly .showin VAlso meshing with the master drive pinion 28,

is a pinion 38, carried by a lshaft 39,001,1- nected in suitable manner, as by sprocket gearing 40, with a hand crank 41,` positioned for convenient vaccess'. -By means of this arrangement, should the motor 37 become disabled, the shaft and flattening Wheel may be manually operated from `the crank 41. Inorder to arrest rotation of the flattening wheel at any time a suitable 'brake may be provided. illustration, the brake is shown'as 'co-mpiising a band 42, encircling the periphery of For purposes of porting iframes47, for said vrollers being adjustable to maintain engagement with the track, by means of adjusting rods 48, having their louter ends connected with adjusting members 49, outside vof the oven wall.

The mantelwalls and cap of the flattening oven may be supported in any suitable manner. It is preferred, however, .to provide the. blocks formingthe mantel walls, with recesses 50, to receive supporting members A51, attached to suspension rods 52, eX-

tending upwardly through the cap of Ithe oven, and secu-red to the'cross pieces 2O .of the supportin frame. In this manner the mantel walls 3 and the oven cap 53 are suspended 'from said supporting frame.

`To protect the shaft 23, `from the intense heat ofthe oven,.the" same `is surrounded by a heat insulating jacket 54, suspended by means of rods 55, attached to the suspending frame, an air space 5,6 being provided between said jacket orsleeve54, and the shaft.

From the foregoing it will be readily understood that a flattening oven is provided inwhieh the flattening wheel issuspended lfrom 'a point above and outside of the oven, and that all of the bearings and driving mechanism are sol positioned that .cient operation. .that deep and expensive cellars are rendered they aie readily accessible, and at the same time they are located at points where the intense heat of the oven can have no detiimental effect upon their perfect and elli- It will be further noted unnecessary, and that repairs may be made at any time without dismantling the apparatus. j A further advantage is obtained by means of the adjustment, whereby the vertical and horizontal elevation of the {lattening wheel within the oven may be convenien-tfly regulated. By providing the manual operating means for the master gear wheel, as well as the mechanical inotoi for actu- 'ating said gear wheel, simple means are pro- Avided whereby operation of the oven will not have to be discontinued should the motor become deranged.

Having thus explained the nature of the invention, and described an operative manner` of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or `all of the forms of its use, the following is claimed 1.
